Is a bad DOA CPU that common?

well I just have to wait and see what they say, if its sent back as testing ok, then i'll see if it runs on the F9 bios, if not i'll sell it to someone with a series 9 mobo
 
wait....why dont you update to that BIOS now? Then youll know if cpu is bad. Have you gone to the board support website?

I think you missed this post #14 much earlier on in the discussion

well I confirmed by bios version is F8 and F8 is "supposed" to fully support the i7-4790 so I don't see how that could be the problem but I upped it to F9 anyway. even though that's said to be just updated for "k" processors, perhaps that was my issue but I highly doubt it.
plus the cpu is half way accross the country already well on its way back to newegg RMA at this moment
 
Naw, I saw it, I misread it somehow. I apologize.
 
mobo has the latest bios and I reset the mobo pins and I pulled it and dropped the i5 back in and all is good so put the i7 back in (just in case it wasn't seated right somehow) and its back in the instant power on-power off cycle so its something wrong with the i7 (internally shorted I'm guessing) and I think its tripping my PSU short circuit breaker protection.

the cpu and computer is the one in my specs so its definitely enough power and its all compatible

for now im back to my old i5 4430

probably take newegg a month to test it and send me a replacement cpu, they are going down hill fast for customer service involving any returns or warranty stuff

As for Newegg RMA ive had no issues, bought a router, it didnt work as a bridge even though it was advertised to work told them false advertising via Chat program and had a UPS label in my email printed shipped and a full refund in 12 days.
 
Neweegg does not test there RMA's (They told me they have no technical training) they return it to the manufacture. Just send it directly to the manufacture in that case.
 
i've had one bad CPU DOA in the last 10 years or so. bought 5x sempron CPU's, one in the batch failed to boot.

I've found dead mobos and dead ram to be far, far more common than dead CPU's.
 
well wait a second here guys, I just realized as we are talking about all this that lets presume im building a new system, now had I just bought this rig, I would have a h87 board that says it runs any i3, i5, or i7 cpu and it will come out of the box with the F5 bios that cant run the i7-4790 cpu I bought.

there is no way for me to automatically know I need a special board with special bios preinstalled in order for it to boot up and so (just for the "what if" query) had I just put this computer together as a budget build, I wouldn't be able to even start the computer in order to reflash the bios to F9 so I would in fact have a setup that says it works together but would "act" as though its DOA and the average computer builder wouldn't know why.

so what the hell do you do if you cant start the computer in order to reflash it lol. something to think about isn't it?

or did they pull all pre haswell refresh mobo off the market? I cant imagine they did

If it has removable BIOS chip you get one with updated BIOS and plug it in.
If it's a "higher end" board it may have USB flashback..or borrow a CPU that works with the BIOS you have.

well I can certainly make contact with you about it, but im not having any issue with your company's response to me having a problem with the CPU and I have already gotten the RMA and it is on its way back to you right now, it should arrive to you sometime tomorrow according to the tracking info so im not sure what more you can do.

everyone I dealt with on this issue has been very nice and helpful so I am not sure what more you can do unless you can speed up the replacement process to get one shipped out sooner to me.

this thread was mainly my way of trying to gage how rare it is to have a bad cpu happen since it never happened to me before in the dozen or so computers I have built and I am not complaining about how newegg has responded to this problem.

after seeing your other posts with almost identical replies to others, time will tell if this is just a canned response by a bot or not

yep, I was just curious if there could be an issue of buying an older version board that says it runs i7 but cant run the i7 refresh cpu until you update the bios.

someone like me who targets 2 or 3 year old versions where prices drop a lot can possibly make a mistake such as this and if I built a computer today im sure I would be buying an h87 type board for it.

but then I guess even these older boards being sold now would (or hopefully should) have newer bios on them already to support the newer i7

Yes it is something you should be aware of. Older motherboard versions even if you buy a new one may need a bios update to support newer CPUs.

That depends on when the motherboard was made.
 
When in doubt, flash the latest BIOS. No if, ands, or buts about it. With new hardware it is very often the case that an issue like this could be a BIOS update away from being fixed. On my latest tower with the P9X79 deluxe and i7 3820, it would power on, hang on the DRAM light, turn off, and do it all over again. I used ASUS USB Flashback to get the latest BIOS on the board and it started without a problem.

I upped it to F9 anyway. even though that's said to be just updated for "k" processors, perhaps that was my issue but I highly doubt it.
Does that mean the F9 update fixed it?

I upped to F9 after the RMA was already in the mail but I had F8 which is the same as F9 but without the k-series overclocking cpu support so there is no reason it shouldn't have worked just fine with the F8 I had on the board.

this is all moot discussion at this point and when I get the RMA replacement cpu back and installed I shall report on it but im sure it was just a bad cpu
 
final update:

finally got the RMA CPU replacement today and everything works as it should.

on another note, as I suspected, the newegg rep who posted in post #35 was just a canned generic response to inform people to let newegg know if you have a problem, well duh !!!

so if anyone is sitting at home confused and doesn't know to contact newegg if they have a problem, then thankfully this person is here to tell you to do just that, but only after other members contact neweggg to tell them they need to come log in to post something lol.
 
It can happen but most computer problems of a computer completely becoming useless are usally created by the computer user. you should be pretty safe if your computer survives past its one year warrenty on its own.
